CS 360 Special Topics: Networking with Android and Java

Introduction

This course is an introduction to Computer Networking covering basic networking architectures, algorithms, and protocols. In particular, it will focus on the 7-layer OSI model and the TCP/IP reference model. This course will discusss, with respect to these models, how data is transferred across a network, how networking protocols allow for open networks and which piece of the model is responsible for each bit of functionality.

Topics

Programming Projects

This course will contain a set of significant programming projects to allow students to gain experience using the networking API available in Java and Android and to understand how the TCP/IP protocol works. Most of the later programming assignments in this course will build on functionality implemented in previous assignments. Quality solutions to the early assignments are the key to success.

All programming assignments must be build in Eclipse.  You may program on Windows or Linux, however be aware that I will test your code on Linux and any or all of the Android devices available in the Lab.  The last project of the semester will use the CISCO routing equipment to explore what can be done on the network router. All projects are individual projects unless otherwise specified, do not allow any other student see your source code.

Academic Dishonesty

1. The cheating policy is defined in the Pacific Catalog as well as the Academic Policy that each of you signed upon entering Pacific University. Be sure you read or reread this policy carefully. All code written for CS360 is to be an original design and an original implementation. The Web, textbooks, and any other references are simply references for you. Copying source code from any source is prohibited unless specifically stated by the instructor. Further, source code is not to exchange hands in any form or by any medium except when sending your solutions to the instructor. It is OK to share high level ideas during the design phase, share information dealing with Java/Android/Eclipse issues, debugger issues, in general, development issues that do not involve code writing.
   
2. Sanctions that may be imposed for academic dishonesty are:
   • F in the course for any form of academic dishonesty

If you have any question as to whether or not what you are about to do constitutes cheating, ask the instructor.

Course Policies

• Assignments are to be submitted, electronically and as a hard copy, by 11:59 pm on the day in which they are due (unless otherwise specified).  Late assignments will not be accepted. Start your assignments early. This course will cover a good deal of new material and writing and debugging the projects will take much longer than you think. You may turn each assignment exactly once.  Source code must be available in Subversion at the due date.
• A program that does not successfully compile or produces no output loses 70% of the assignment grade.
• Grade Complaints: If you have a complaint regarding a grade on an assignment, exam, or homework, write a one paragraph description of why you feel the grade is incorrect and deliver it to the instructor. The paragraph must be delivered to the instructor within one calendar week of when the graded material is returned to the student.
  
• No early or late exams/finals will be given.
• No incompletes will be given.
• All code in any form generated from this course becomes the intellectual property of Pacific University. You may not share this code with anyone without obtaining written permission from Pacific University.
• Neither computer failure, software failure, nor lack of computer access are accepted as excuses for late programs; therefore, start work on the programs as soon as they are assigned, don't put them off until the last minute. Further, corruption of programs due to bad disk media is also not accepted as an excuse for late programs; therefore, always keep a current backup of all programs on a separate disk.
• The instructor reserves the right to raise or lower a student's grade based on class participation and attendance. Specifically, participation can raise or lower your final grade by 1/3 of a grade. Further, your final grade may be lowered by 1/3 of a grade for each day (or portion thereof) of class missed. Please notify me PRIOR to class if you must miss class for any reason. Only legitimate reasons will be accepted as excuses for missing class
• I do not want to hear any electronic devices go off during lecture; therefore, make sure you silence these devices before lecture starts.
• Class starts promptly at 2:15 pm. Your attendance is expected at each class meeting. It is in your own best interest to attend class, as your grade will almost certainly suffer indirectly if you choose not to attend. In addition, I reserve the right to consider attendance in instances of borderline grade assignments. Of course, excused absences (sickness, family emergencies, varsity athletic participation) will not be held against you. Scheduled absences should be communicated to me well in advance. If you must miss a class, be sure to check with me or another student to get what you missed. Exams will be given in class on the day scheduled and may not be made up. The material in the course is, by necessity, cumulative. Be warned that if you fall behind, you will not be able to catch up easily.
• If you have a documented disability covered under the ADA then services and accommodations are available from LSS (Learning Support Services). If you need reasonable accommodations to fully participate in course activities or meet course requirements, you must contact Edna K. Gehring, Director of LSS , at X2107. She will meet with you, review the documentation of their disabilities, and discuss the services Pacific offers.
